Role of enkephalin derivative in promoting wound healing and scar remodeling via increased epidermal growth factor in a mouse model [PDF]

open access: yesArchives of Aesthetic Plastic Surgery, 2023
Background Enkephalin, an endogenous neuropeptide, binds to the delta (δ) opioid receptor and exerts an antinociceptive effect. Recent studies have suggested that neuropeptides might effectuate cutaneous wound healing.

The role of enkephalinergic systems in substance use disorders

open access: yesFrontiers in Systems Neuroscience, 2022
Enkephalin, an endogenous opioid peptide, is highly expressed in the reward pathway and may modulate neurotransmission to regulate reward-related behaviors, such as drug-taking and drug-seeking behaviors.

A drug delivery strategy: binding enkephalin to asialoglycoprotein receptor by enzymatic galactosylation. [PDF]

open access: yesPLoS ONE, 2014
Glycosylation of biopharmaceuticals can mediate cell specific delivery by targeting carbohydrate receptors. Additionally, glycosylation can improve the physico-chemical (drug-like) properties of peptide based drug candidates.

‘Acetaldehyde‐enkephalins’: elucidation of the structure of the acetaldehyde adducts of methionine‐enkephalin and leucine‐enkephalin [PDF]

open access: yesFEBS Letters, 1980
The two major endogenous opioid pentapeptides, methionine-enkephalin and leucine-enkephalin [ 1,2] rapidly react with acetaldehyde, under very mild conditions, to give an ‘acetaldehyde-enkephalin’ adduct, referred to as ‘acetaldehyde-enkephalin [Met’] and ‘acetaldehyde-enkephalin [Leu”], respectively 231.

Opioidergic pathways and kisspeptin in the regulation of female reproduction in mammals

open access: yesFrontiers in Neuroscience, 2022
Endogenous opioid peptides have attracted attention as critical neuropeptides in the central mechanism regulating female reproduction ever since the discovery that arcuate dynorphin neurons that coexpress kisspeptin and neurokinin B (NKB), which are also

Endogenous Opioids in Crohn’s Disease

open access: yesBiomedicines, 2023
Caring for patients with Crohn’s disease (CD) is a serious challenge in modern medicine. The increasing incidence of CD among adolescents and the severe course of the disease create the need for new methods of diagnosis and therapy.

The Enhancing Effects of Peptidase Inhibitors on the Antinociceptive Action of [Met5]Enkephalin-Arg6-Phe7 in Rats

open access: yesJournal of Pharmacological Sciences, 2007
Previous in vitro studies have shown that the degradation of [Met5]enkephalin-Arg6-Phe7 during incubation with cerebral membrane preparations is largely prevented by a mixture of three peptidase inhibitors: amastatin, captopril, and phosphoramidon.
